A more upright lie in irons. You can not move enough weight far enough in an iron to create the “draw” bias some talk about. Offset helps as well. More offset. Again, with irons, more upright, a cg more towards the heel (don’t know why anyone would want that in an iron), and more offset would be the things to contribute. In a driver, you can move a higher percentage of the weight of the head, and more weight, to the heel so it could help more, however an upright lie would still be more of an influence.
